然后采用IFFT算法和自适应数值积分算法计算二维积分，得到了低音速、跨音速和超音速移动荷载作用下动力响应的数值结果。
Coupled IFFT algorithm and adaptive quadrature algorithm was employed to compute double integrals in the analytical solutions. All the subsonic, transonic and supersonic cases were computed.
如果飞得太快的话，升力的中心会向机翼后部移动，使飞机的机头朝下，导致飞行速度增加，直到飞机接近音速。
If you go much faster, the center of lift moves back on the wing, pushing the nose down and increasing velocity, until you soon approach the speed of sound.
对于他的超音速自由落体的企图，鲍姆·加特纳将退出移动平台。
For his supersonic freefall attempt, Baumgartner will be exiting a moving platform.
我们没有注意到这一点的原因是空气分子以音速在不停地移动，而当它们碰到任何表面时都会反弹回去。
And the reason we don't notice all this emptiness is because air molecules are constantly moving around at the speed of sound, and bouncing against any surface that happens to fall in their path.
一种是通过爆炸，即火苗以超音速向前移动从而产生剧烈爆炸。
One is via detonation, in which the flame front moves at supersonic speed and produces a powerful blast.
